For some of Marvel's less powerful and/or more obscure heroes and villains, how would you add to expand their power set.

Havok: Can create energy shields for brief periods and create energy spheres that hit fast but don't do as much damage as his beams.

Tigra: In human form, she can channel her "tiger side" without transforming. Her Tigra gets stronger putting her on the level of Kaine. She also gains the ability to transform into a tiger and is faster in this form.

Puma: Can transform into a normal-looking puma.
