Lio

SpaceTech has created the best battlefield companion for you — one that ensures universal protection exactly when you need it most. Every time Lio or its ally takes damage, Lio accumulates armor bonuses which are transferred to its linked partner. These armor bonuses are permanent and remain active throughout the entire match. Oh, and by the way, Lio can fly. Seems like you have every reason to be a little afraid.

ABILITY

Fortress Link The robot takes off, gaining several charges of CounterSuppression. If an ally is nearby within your crosshair, Lio establishes a link with them and also applies several charges of CounterSuppression.

Each time Lio or the linked ally takes damage, Lio accumulates armor bonuses, which are also transferred to the ally. When the link is broken, the ally loses the armor bonuses, but Lio retains its armor points.
