# Exact mechanics are less important than control

No matter how the exact transformation works the key thing that matters is how it is controlled. A scientific device, a superpower, and a magic wand, all fundamentally work the way just in different settings. You really need to choose between the following three styles of ability:

- **At will.** The character is in control of their transformation. They can switch back and forth whenever and wherever they choose. The character can use their alternative forms strategically and plan to make the most of the abilities of each form. This makes the character stronger and capable of achieving things neither form could alone.
- **Forced.** Werewolves at full moon, Fiona from Shrek, characters with specific triggers (often based on the moon or time of day) that force them to change, usually against their will. These type of transformations are more often described as a curse than a blessing. Stories involve characters learning to deal with their curse and overcome it, succeeding despite their curse rather than because of their superpower.
- **Emotional.** The Hulk is the ultimate example here. These characters transform based on how they feel in a given moment. It is difficult to predict when the will transform and harder still to control when they do. The common trope is that these characters learn to control their emotions and transition to at will transformations.
- **Something else.** These are just a few examples of how a transformation ability works, you can likely imagine any number of other complicated triggers. Ultimately it comes down to how the character can control/understand their ability to transform.

Another important thing to consider is how the character view their transformation. Is it a blessing? A curse? Do they despise their other form or view it as their secret weapon? Would they give up the ability if they could? These feelings with inform your character development and the narrative you tell from it.
