I'm sorry, I'm so so sorry... I'm pretty sure that's my Mega Man.

I knew how powerful some of Shadownico's robots were. He defeated a couple of my robots with his own robots that had 9999 each for his stats. I plan to beat him back at some point, but anyway, this is not a bug. The robot's stats are legit. You can reach 9999 by continuing to grind your robots after they hit level 100.

Either way, you can easily defeat robots like those with Energy Swap.

I was just paranoid because of the Invincible Mecha glitch... but that's already reported.

Yeah, not really a glitch - just how things worked out for some people. When the game was still in the (very) early stages of development, gaining levels and experience was significantly easier than it is now. It might seem unfair for some people to have higher battle points and levels than everyone else if they technically had an easier time doing it, but I like to think of it as more of a perk/benefit for being an early adopter. It's still technically possible for even the newest member to get a full team of 9999 robots, it'll just take them a little more effort. :P

I'm glad Shadownico's Megaman and Protoman has 9999 in all their stats. Rain flushing his team to death yields some very nice stat boosts for my Copy Core and Water Core robots. Though his Megaman's Top Spin is often lethal, so it's not always easy.

Like Ageman said, it is possible for anyone to gain 9999 in every stats. With Player Battles and the Bonus Fields, it is pretty easy for 1 strong robot to gain 50-100 points in every stat in a single battle, if you use it to take down the entire enemy team.

Even on strong high-stat robots on Player Battles my LVL 100 only gets 10-30 stats for each
