The wikis claim that difference between power armor and power suit is that the latter doesn't cover the whole body like full-body armour. Samus is even given as an example of power armor. The problem however, is that Samus' armour is in fact named "Power Suit" in the games, and because of this people just tag power_suit on Metroid posts, using it as the name of the armor and not as the gentag it's supposed to be. Arouund a third of power_suit posts are in fact Samus' power_armor.
I think we should have a power_suit_(metroid) tag to differentiate Samus' unique power armour to reduce mistagging (and imply all the suit variations to it while we're at it).
The problem unfortunately goes deeper than Metroid since there are like 600 posts (not counting Metroid ones) that are tagged with both power_suit and power_armor, when only one of them is valid, so a lot of gardening would be required.
