Chaquetrix

The Chaquetrix is an alternate Omnitrix from a fan made alternate timeline where instead of turning the wearer into an alien species it instead creates a member of the selected alien species that is slightly altered to the wearer's personal preferences in a mate. All aliens are of maturity for their species, at least 18 years old. The summoned alien has a unique personality but no memory until they are summoned the first time, afterwards they keep memories from all previous summons. (I.E. If you introduce yourself the first time an alien is summoned it will remember you and what it did all previous times it as summoned)

If Master control is unlocked then it allows multiple aliens to be summoned at once and kept out indefinitely.
