Overview
Contender is a HG with a forced retarget Skill.
Contender’s Skill applies a large Vulnerability debuff on a specific target, depending on her position when she activates her Skill. After aiming for 1s, she then fires a special bullet that forces all allies to focus on said target. Along with her pretty decent tiles, this makes her useful to help your Echelon eliminate a single key target.
With her SPEQ, Contender also stuns all enemies upon her Skill’s target dying. While not too useful in general content, this can be a very nice option for some Ranking fights. Do note that a lot of newer enemies are immune to stuns, so usefulness varies greatly depending on enemy teams.
With all this in mind, Contender is niche, but a good option to have.
