I dont know very many 20pt figures that can hit for 4 damage. He has his regular attack and then however many you can put power actions on your sidekicks for. VERY much worth his points on a sidekick swarm team.

He can only make one extra attack a turn through Sidekicks.

Oops, you are correct. You can only chose one that hasn't been chosen yet. Even still though he is very strong. Every turn you can get an extra attack if you got enough side kicks, even when he's pushed out he can be swinging.

Strongest common of the set. In some sets it would be a steal already having 4 clicks of invulnerability with those values at 20 points.
Add a sidekick to give him a full move and then attack ability, makes him bonkers

Wow, even without the extra move and attack options sidekicks provide this guy is nuts. He is a serious threat for only 20 points.

[Errata]REMOTE-CONTROLLED GAMING FUN!: Friendly Sidekicks have: "POWER: Choose a friendly character named Thing Robot and one effect that hasn't been chosen for that Thing Robot this turn: Move Thing Robot (up to it's speed value) -or- Thing Robot makes a close attack."

What did they do, just slip this in there? I thought I was up to date on errata from freakin' 2021!
