Life expectancy is usually from 5 years to 628 years, according to studies and observations, some show no signs of aging and other age to quick. It may be something to do with what species or even what methods were used to create you, not a lot is known.

Most experiments have a neutral alignment or none at all, they just go by what their creator or "soulmate" do. They don't have a sense of evil or good.

Your size depends on what the base species where used to make you.

Your base walking speed is 30 feet.

You can see in dim light within 80 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You can speak, read, and write Common and 1 more language.

You choose one characteristic now and a second at 5th level. Since some experiments can develop some hidden genes.

At 1st level, choose one of the following options:

• Glide - When you fall and aren’t incapacitated, you can subtract up to 100 feet from the fall when calculating falling damage, and you can move up to 2 feet horizontally for every 1 foot you descend.
• Climber - You have a climbing speed equal to your walking speed.
• Extra Appendages - You can use the grapple action as a bonus action

At 5th level, your body evolves further, developing new characteristics. Choose one of the options you didn’t take at 1st level, or one of the following options:

• Carapace - Your skin in places is covered by a thick shell. You gain a +1 bonus to AC when you’re not wearing heavy armor.
• Acid Glands - As an action, you can spray acid from glands, targeting one creature or object you can see within 30 feet of you. The target takes 2d10 acid damage unless it succeeds on a Dexterity saving throw against a DC equal to 8 + your Constitution modifier + your proficiency bonus. This damage increases by 1d10 when you reach 11th level (3d10) and 17th level (4d10). You can use this trait a number of times equal to your Constitution modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.
