Skrull infiltrator gives you more for same points. These guys are strictly for the sideline where they are free or for generation by Hulkling/Super Skrull/Veranke. Depending on what sidekick bonuses you have they could be more valuable though. Besides a 50/50 shape change they just dont have much else going for them. Weak stats, no defense but hey, free is free.

This could be fun.

have Hippolyta on your team and then, they come in from Sideline, they just need to make one hit and click up to having stealth and shape change

I doubt this guy is going to win any tournaments - but still a decent way to fill 20 points shy on a team build.

Fun and cheap! Starts with a strong 4-6 Shape Change and Stealth and has the flexibility of a side kick. If you've got sideline room then just toss 1 or 2 on your team for a chance at reinforcements! Never know when you might need that extra tie up piece or maybe that little bit of extra damage!
