[quote=@Hantu Kongkek] On Devil Triggers. They do "unlock a character's true demonic form", yes. But it's not like Arrancar in Bleach, where it's a form change/stat boost. In the DMC games, it's sort of a panic button. Healing tends to be far slower than what you lot seem to take it for. There is also a stat boost, but again, the statboost is marginal. The more tangible changes are towards moves; that is, one or two per weapon. For instance: Stinger, which would go through an enemy as opposed to knocking them back as usual. Sometimes, it also prevents knockback which can be pretty useful depending on situation. [/quote] That's only based on gameplay, and that's also only from the player's perspective. The Devil Trigger acts as many different things, Dante has demonstrated that it can be both your true demon form, or your link to your weapon. In DMC4, Dante demonstrates it as being his true demon form. In DMC3 and DMC1, he demonstrates it as being his link to his weapons, where his form actually changes when he changes weapons in that game. In DMC1, he unlocks a unique one from using the sword Alastor. For enemies, it's probably more accurately a ramping up power-up. When fighting enemies in Dante Must Die mode, they will Devil Trigger if they are not killed within a certain time limit, giving them higher power, lower rate of stagger, and sometimes additional abilities. So, DT can be anything really, it's possible to have multiple even. Normally it's unleashing a latent power, or some kind of super form, it doesn't always have to be your true form. It is also only limited to demons, so keep that in mind too. Next, demons taking human form is just a preferential thing. Most don't take a human form due to pride in their true form and as demons, or they are simply unable to take a human appearance. Powerful magical abilities can allow them to on the other hand. I would assume Lily and Blair are of the same brand of demons as Sparda, who takes a human appearance first before his demonic appearance. Shapeshifters like Trish can change appearance at will, she probably could take a non-human appearance but takes a human one out of preference.
