I give you an extra nerdy chapter: the team meets Ace the Bat-Hound!

The whole team plus Zatanna, Rocket and Wolf are in this, there also may be mentions of Batgirl who is in training a at this point.

So, I am putting my own spin on Ace's story so go with it (the joys of fanfiction).

Just a thought to keep on mind, Ace and Wolf are going to be pretty protective of Robin as I find that really cute, especially as both dogs are bigger than him. To them he is their little pup.

I don't own any of the animals, they are real, it took some research to find them though.

Anyway hope you enjoy.

Robyn 

It started with a squeaky dog toy. The toy in question was a small black bat that squeaked anytime you applied pressure to it which made it the perfect dog toy, especially for crime fighting bat themed dogs.

It was thrown through the Zeta Beam into the entrance hall of the Mountain where the team had just arrived. They had been chatting away happily, catching up on the latest gossip in each other's lives when the weird squeak drew their attention. They all turned around curious to see what the sound was, only to find the dog toy lying near the zeta-tubes. They all stared blankly at the dog toy confused, before Robin groaned knowing what had happened.

Wolf lifted his head from where he had been lying down, he'd been there to greet the others who came through the zeta-tube but had settled down when everyone had arrived. He slowly pushed himself up onto his feet, stretching, before gingerly trotting over to the toy, curious to the familiar noise. He nudged the toy with a lazy paw before leaning down to sniff it. He turned back to look at the watching team as if asking for permission or an explanation before turning back to the toy.

Just at the very second he was about to lean down and claim the toy as his own, a large black monstrous shape leapt through the zeta beam. It grabbed the toy away from the shocked wolf then bounded over to Robin. Robin had his eyes closed as if begging the universe for the attack he knew was coming to not happen. Unfortunately the universe clearly wasn't listening as the monstrous shape leapt onto Robin knocking him to the floor.

The team and Wolf swiftly jumped into action at seeing the monstrous figure knock down their youngest member. They had no idea what was happening or what the shape was but clearly it knew Robin. They moved forward to try and save their youngest member but froze once they heard Robin laughing.

A second later Robin looked up to see his friend's questioning glances, he rolled out from under the figure and stood up, wiping away imaginary dust. On closer inspection, and without the new comer moving, it was easy to see that it was a large dog. It wore a yellow collar with a bat-symbol tag hanging from it, and a black cowl covering its face, which ended in a cape that covered most of its body.

"Who is this Robin?" Kaldur asked on behalf of the team who were all standing around confused.

"Everyone meet the Bat-Hound!" Robin waved his arms in the direction of the figure, who was now standing at his side, like a magicians assistant. The dog had its tongue out, panting, and looking very happy with itself.

"Wait, even your dog has a secret identity and fights crime? Dude, what is it with you insane Bats?" Wally exclaimed, arms waving around to emphasise his point.

Robin simply grinned. "The Bat Hound isn't a normal dog though Wally. He is a specialised crime fighting dog, we took him in when his former master was kidnapped, he helped us find him. He was a natural. His master took on a new job that meant he couldn't look after him so we kept him. Like every Bat he received training, before joining as the Bat-Hound!" Robin exclaimed with proud smirk on his lips as he rubbed the large dark brown German Sheppard's head.

"I was about eight when he joined us, he saved my life soon after that and he's been protective of me ever since. Oh and Wally, us Bats are not insane, we are awesome!" Robin continued explaining as he strolled out of the entrance hall towards the kitchen.

The Bat-Hound (which was quite a long name to call a dog but the team didn't know his real name, well if he had another name) followed the young bird with his eyes, keeping him in his line of vision until he was completely gone. He then turned around and padded over to Wolf. Both animals sat opposite each other and seemed to have a starring contest for a while until the Bat-Hound gave Wolf the dog toy which had started this mess in the first place. That seemed to break the ice as the pair started greeting each other in earnest.

The team stood watching the animals bouncing around having fun completely emerged in their own thoughts. They were all so thoughtful that they didn't hear their youngest team member come back in, and only registered his sudden appearance with a startled jump when he waved a hand in front of Wally's face, which sent off a chain reaction.

"Woah, I didn't know any of you could be this quiet. Especially with Arty and Kid Noisy in the same room." Robin snickered as he lay a bowl of water in front of the now still animals, unlike the heroes they had noticed Robin's return and calmed down.

"Hey Robin, how did he even get through the Zeta Beam?" Raquel asked curious. It had been one of the biggest questions in her head as she watched the dogs play.

"Batgirl probably threw the toy through during training." Robin shrugged, hiding a grin. He knew exactly what kind of reaction that statement would get.

"Who's Batgirl?" M'gann piped up having been silent up until this point.

"A friend who is in training to be a hero." He answered his grin becoming more obvious.

"By that he means another member of the Bat family." Wally announced dramatically.

"Wait, the Bat Family?" Connor questioned watching Wolf and his new friend.

"Yep, it is the name given to all the Bats. The group includes Agent A, Batman, Robin, Bat-Hound and Batgirl apparently now." Wally grinned enjoying getting to tease his friend and being the only other person vaguely 'in the know' about the mysterious Bat Family.

"Anyway, getting back on track. Why would she throw it through the Zeta Beam?" Zatanna asked.

"Well it a long story..." Robin stretched out, enjoying trolling his teammates.

"Than shorten it." Kaldur sighed.

"Batgirl and I are in the middle of a prank war and she most likely saw me come here and threw the toy through knowing I would then have to explain. She's probably stalling so she can think of a better prank." Robin announced dramatically.

"That wasn't that long of a story." Artemis scoffed but couldn't hide her grin.

Robin looked back down at the animals that had started playing around again, wrestling each other this time trying to see who was stronger. A sudden thought occurred to Robin, a thought so amusing that he let out a loud laugh, causing everyone, including the dogs to stop and look at him.

"Hey dude, what's so funny?" Wally asked scrunching up his eyebrows.

"Oh, I was just thinking that we should make a team of hero animals, who would fight a team of villain animals." Robin stated between laughing.

"What the Justice animals versus the... what would the villains call their team?" Wally asked seriously.

"Dark Animals or the Vengeance Group, or maybe Animal Light." Artemis suggested sarcastically to the two maniacs.

"No those sound stupid. We'll have to think of something better later. Who would even be part of the hero's team?" Wally waved Artemis away, not noticing most of the team roll their eyes at their antics.

"Well Bat-Hound, Wolf, Krypto the Super dog-." Robin started listing, ticking them off his fingers as he said their names.

"Wait, Superman has a dog?" Connor cut in frowning.

"Yep, Bat-Hound and Krypto have a similar relationship as Batman and Superman." Robin nodded still trying to think of hero animals.

"He has a dog but doesn't want me." Connor asked his eyes trying to hide the pain he was feeling.

"Sorry Conner, but don't worry Bats and I have a plan for if Superman doesn't get his head out of his a-"

"Robin!" Kaldur warned.

"Nose, I was going to say nose!" Robin grinned, making it clear to everyone that he definitely hadn't been. It had done its job though and got Conner to stop frowning.

"Anyway back to the list." Wally prodded, he was curious about the animals and so far they only had dogs.

"Maybe Hoppy, the Marvel Bunny and Beppo the Super-monkey, Comet the Super-horse and Streaky the Super-cat." Robin added, thinking hard.

"Lots of Supers. How do you know so many animals?" Artemis intervened before Robin could continue listing animals that no one else had ever heard of.

"Stop interrupting me. Batman keeps an eye on everyone, duh. Now, back to the list - Topology, Aquaman's octopus might help if they do under the sea missions." Robin continued, ignoring the rest of the team.

"What about the villain's team? Which we still need a name for." Zatanna decided to take part in the discussion now, giving a shrug as an Artemis' incredulous look.

"Well Gorilla Grodd, if he counts. Isis defiantly, she is Catwoman's cat. Bud and Lou, Harley's hyenas would be interesting. That's about all I can think of right now though." Robin concluded, sitting down on the floor Bat-Hound on one side and Wolf on the other.

"I can't believe you two actually think it is a good idea to have a team of animals fighting for us." Artemis sighed.

"I can." Raquel snickered.

"Any who, I need to get Bat-Hound back home so I will see you guys later. I need to prank Batgirl and feed the Bat Hound. Bye." Robin waved as he left the mountain followed by the black figure of the Bat Hound before anyone could stop him.
