I beat him but it took a chemical cloak to do it. I would rank him a little bit higher than Hard.

It would be nice if new opponents weren't just blank images at battledome. Someone please fix it.
if you end up with only 1 scroll left, it turns to gate of evil. I did notice the cloak was great too! And no, the felibot doesn't give items, sorry ^^; I did love getting the head, another kitty item, even if it does look a bit like an american football

It seems x_Crackdown_x and M4-L155 are equally matched! Maybe you should train a little more, and try again.
gosh darn it!!!

surprising since this pet has stats of only 112
How come I can't see the images for this or the other new challenger in the battle colosseum? The names are there but there's no image, and when I fight them there's still no image.
does felibot give stuff?
Congrats faerie favors! I have a chimerical cloak for my HA but never used it in battle.

Woot. A chimerical cloak is awesome for this thing.
Since I got him down to 26 HPs I might be able to beat him if my pet had spells. What's a good healing spell for 8 APs? Oh and congrats to those people who beat him, that's great!

I'm so not beating that.
D= Anyone else have there scrolls turned into Gate of Evil Scrolls when battling him?
Well actually I just got him down to only 26 HPs, which surprised me because my best pet is about half his stats. But still not good enough. Guess I won't be seeing that prize. Maybe if my pet had some spells, he has 8 APs but I don't have any spells.
I thought this was a new pet... xD It would be pwnsome to have a robot kitty in the family... BD
Wow, even my strongest pet, who I've been training constantly for months, isn't high enough stats to fight this one.
I like the minion he gives out! But... I'm selling it. xD All of my pets have minions already.
leet Maliss... sigh
I thought the Internet was done with that whole 'leet' thing...
I thought this was a new pet or something laughs. Does anyone else think the robot head looks like the luna ball from sailor moon?
OMG I was thinking that too!!! Does anyone know what you get for defeating it?
I thought it was a new pet ;; I want one. When they'rll all defeated have a little message something like 'The M4-L155 have been defated and now know the strength of subetians and have decided to join our side. You can now go adopt them!' or something ;;
Oh my - I was thinking it was a new pet too... and if it was I would definitely want one!!!
Looks like I wasn't the only one who thought that this was a new pet.. ^-^;;

Was kind of easy 
this would be a cool experiment pet-and so would a new color of robot! robot kumos and robot fester etc (my pets weapons and stats are way too low to bother fighting this one!)
This would be an awesome pet, yes. I was kinda hoping it was one, actually. I'm still trying to beat pock, saper and riscors 20 times.
I was so hoping this was a new experiment pet 
LOL you're right! It's an Elite Maliss. Ahem... I mean... 1337 M4-L155. 
Wow I got clobbered in just 2 hits lol 
. That is one very impressive battle opponent . Great job .
Scaaaaaaaaaaaaary~ goes to fight anyway
look a it closly and the name is like maliss
Wow, looks awesome.
BTW, it should be "unleashing"
About to head to bed but checking the news first, I thought the same thing as Siyana and Twixy... "I want one of those" I'll have to try beating him in the morning.. well, later in the morning anyway.
I beat one and got the head, waiting to see what it will do though =u=
Grrr, I'd love to be the one to take this guy out.
You call that "hard"? Compare those stats to the ones in "very hard" or even "extremely hard".... Yeah, there we go.
XD
For a split second I was like, YAY NEW PET I WANT ONE
Hmm.
Bet I can't beat it XD

XD Not wearable. Ah well
I wish they'd released this as experiment pet
