Catch the Rainbow

Catch the Rainbow (キャッチ・ザ・レインボー) is the Stand of Blackmore, featured in Steel Ball Run.

Appearance
Catch the Rainbow Manifests itself as a mask worn by Blackmore. A heavy  of a vaguely troubled angle hangs over its eyeholes. It has no nose, and in the region of the mouth it bears a row of five long, vertical slits, dotted by five holes.

Light overall, it is marked by three colorful stripes crossing from its left eye to its right cheek. The stripes were designed to be a rainbow version of a hockey mask.

in the colored manga, Catch the Rainbow is white with blue, green and red stripes.

Abilities
Catch the Rainbow functions as an ability for Blackmore, who personally deploys his control over rain to fight. Although providing very powerful abilities in heavy rain, the Stand has one major drawback; it requires a natural rainstorm to occur over its user and continue during its usage. If the rain stops while active, all current effects that Catch The Rainbow is producing will disperse and the Stand will become relatively useless, only remaining in its physical mask form until another rainstorm starts. The rainstorms in question must be completely natural, attempts to emulate rainfall over Catch The Rainbow are stated to not activate the Stand.

Rain Manipulation
Catch the Rainbow allows its user to utilize or manipulate rain in various unusual ways.

The most basic ability of Catch the Rainbow is to stop raindrops in their tracks and make them float in mid-air, becoming solid enough to support Blackmore and also deflect projectiles such as a Steel Ball. With this, Blackmore is able to tread on them and reach high altitudes. He can either stop a few select raindrops to walk on, stop several of them over a large zone or create blades out of them. If a target attempts to move through rain stopped by Catch the Rainbow, the drops will tear and penetrate them, potentially creating fatal wounds.

Blackmore is also able to meld with rain. He can let the raindrops fall through him and create holes in his body, with the disappearing body parts materializing from the same raindrops at a distance from the body and remaining functional despite the separation. For instance, he can project his mouth at a distance and talk to someone. He can fuse entirely with the rain and becomes intangible like water, able to evade gunshots, but also travel at high speed across great distances as long as there is rain.

Blackmore demonstrates the ability to plug his wounds using raindrops and stem all bleeding, although it is only a temporary measure as said raindrops would lose the power enacted upon them should the rain cease.
