Hot Wheels Battle Force 5
 

I wish they added a season 3. So far for new members Tezz & AJ are the only ones.

For the power cells:
Tezz (Stanford's)
AJ (Sherman & Spinner's)

So far Vert's, Agura's & Zoom's are the only ones left. Once complete there'll be two units of Battle Force 5.

I can picture Grace being part of the team in a pink battlesuit.

Vert & Saber - Leader
Agura & Tangler - Hunter/Special Operations
Sherman/Spinner & Buster - Strategy Tactician & Tech Support
Zoom & Chopper - Scout
Stanford & Reverb - Weapons Expert
Tezz & Splitwire - Strategy Tactician & Electromagnetism Expert
AJ & Gearslammer - Survival & Terrain Expert

Picture Grace joining the team as its medical officer? Taking Zoom's power cell.

Plus a new vandal but joins the good guy. A bird-like one who wants to remove Kalus of leadership and become a new one in making its race a peaceful one.
