Tahnok-Kal is pretty skilled and his thunder abilities may prove to be useful…just not in this fight. I think that they could still damage Pohatu and possibly overwhelm his normal form, but we can’t forget about fusion. Also, Pohatu is still a fighter in his normal mode and wouldn’t go down without a fight. Tahnok-Kal’s weakness is that he’s essentially a one trick robot and doesn’t have many backup options. Pohatu wins.
