The Resize power set allows characters to grow and shrink dramatically at will. The most common way for this to happen in the Marvel Multiverse is by use of Pym Particles, named after the scientist who discovered and developed them: Hank Pym (Ant-Man, Goliath, Yellowjacket and so on). When using Pym Particles to shrink, a character’s extra mass is displaced into a pocket dimension. Because of this, the character retains many of the same qualities they have at their full size, like their strength and durability.

Pym Particles are usually stored and dispensed to the character via a mask or kit, which gives them the Tech Reliance trait. However, after repeated exposure to Pym Particles the bodies of some characters begin to produce them spontaneously, removing that trait. When creating a character, you can pick which way you’d like to go, but higher-rank characters are more likely to go without the Tech Reliance trait than lower-rank ones.

The Resize Effects table shows which powers it takes to achieve various sizes. It also shows the modifier to the character’s Melee and Agility defenses at that size, the damage multiplier the character gets to add to their Melee attacks at that size, and the effect their size has on many other things.

The defense modifier can also be applied to other checks where size makes a difference, like someone trying to spot the character while they’re sneaking or hiding. If the character is tiny size, for example, they add the +3 defense modifier to their Agility defense when people try to spot them.

Damage multiplier bonuses from size do not stack with other damage multiplier bonuses. Apply the biggest modifier instead.

For simplicity’s sake, don’t worry about resized characters’ relative sizes, like a gigantic-size character versus a miniature-size character. Just apply their regular defense modifiers and damage multipliers as listed.

Example: Ant-Man shrinks from average size to miniature size, making him about as tall as a miniature on a gaming table. He adds +4 to his Melee and Agility defenses.

Apply a character’s size multiplier to their reach, the number of spaces they occupy, their speed and their throwing ranges (as shown on the Objects & Sizes table at the end of Chapter 4). A character that is little-size or smaller doesn’t occupy a full space. Because of that, they can share a space with other creatures. In fact, if they want to make a close attack, they must be in the same space with their target, as they cannot reach outside of it.

The number of spaces a character occupies is the length in spaces on each side of the cube they occupy. A huge-size character, for instance, occupies a cube that is 5 spaces on a side. Characters can come in different proportions, of course, and the Narrator should make adjustments for ones that are longer, taller and so on.

Resize Effects

Example: Ant-Man changes to little size. His reach is now (1×¼, rounded down =) 0 spaces, which means he can only reach things in the same space as him. He normally occupies 1 space, so that’s down to 0 as well.

His Run Speed is normally 5, but it’s now (5×¼, rounded down =) 1 space. His range for throwing something three or more steps smaller than him is normally 20, but now it’s (20×¼=) 5 spaces.

Example: Giant-Man grows to gigantic size. His reach is now (1×20=) 20 spaces, and he occupies a cube that’s 20 spaces on a side as well.

His Run Speed is normally 5, but it’s now (5×20=) 100 spaces. He picks up and throws an airliner, which is the same size as him. For an average-size person throwing something their own size, the range is 5 spaces. For Giant-Man throwing that airliner, it’s (5×20=) 100 spaces.
