TikTak

The TikTak twins are a pair of identical mimic metahumans. Tik and Tak can copy a person's shape and powers, along with some memories. They're from an alternate universe, recruited by an evil Porter variant that tried to take over the world by hijacking the moon.

They're an alternate version of the former teen hero duo KitKat. Kit and Kat have the same power, but split up when Kit decided to use her powers for personal gain. Kat eventually became the heroine Copycat.
