Beef was a mostly pointless character, a complete Z list character. He was in 2 issues of New Warriors and 1 issue of X-men. He barely even said anything!!! Have you even read the issues???
All his powers was were super strength, and he was only created to replace Thunderbird II/Warpath after he reformed and left the Hellions. Just like how Bevatron was created to replace Firestar (he also only ever made 3 appearances).
The only thing that was ever learnt about them was....
-that they were Hellions.
-there mutant powers.
-there codenames (never even learnt their realnames).
-Beef wasn't intelligent, and was quite dim.
-Bevatron spoke in a french accent.
THATS IT!!! SERIOUSLY!!!! The other Hellions had way more characterisation.

Also Shard is DEAD!!! because with Bishop absorbing her as an Energy being he kills her, BEFORE he shoots as his energy beam. Just because your energy doesn't mean your still alive...there is a difference between being an energy 'being' and 'energy'.
Beside Joseph Harriss (the writer), confirmed in interviews that Shard was dead in his mind.
