I worked up a 4x6 index card 5e character sheet.

These days I prefer a game that I can fit the whole sheet on a 4x6 card, so I guess 5e succeeds there.

Styracomen - a race for 5e

I feel like I'm writing an 80's toy-line cartoon with this stuff.

Styracoman
Ability Score Increase: +2 Con and +1 Str.

Super Fucking Tough: Your hit point maximum increases by 1, and it increases by 1 every time you gain a level.
Age: Styracomen mature by 8 years old. Most adventuring Styracomen are 10-15 years old. They can live to be around 50 years old.

Size: 6 ½ to 7 feet tall usually.

Alignment: Styracomen tend toward Chaos. They are hot-headed and rarely think about consequences. They’d rather headbutt whatever is in their way.
Speed: 30 ft.
Horns and Frill: A Styracoman can make a charging attack that knocks her enemies to the ground. If you move at least 15 ft in a straight line at an enemy, you may make an attack with your horns. On a hit the target takes 1d10+Str bonus damage and you can make a shove attempt (Basic, pg 74).
About Styracomen: Young adult Styracomen are kicked out of their tribes between 8 and 10 years of age. These wandering young often seek adventure for a time before founding their own herd or joining another. Only slight variation in frill coloring distinguishes the Styracoman sexes, non-Styracomen cannot tell the difference. 

Stegomen - a race for 5e

First in a series of posts on humanoid dinosaur races for D&D 5e.

Stegoman
Ability Score Increase: +2 Con and +2 Str (if it's good enough for dwarves, it's good enough for Stegomen).
Age: Stegomen count their age from the first ancestor in their racial memory. This makes no sense to non-stegomen.
Size: 7 ft tall when standing as straight as they can get. The tail, which is very flexible, is another 5 ft long.
Alignment: Stegomen are lawful, following the ways of their ancestors.
Speed: 25 ft.
Natural Armor: Stegomen cannot wear armor, but may use a shield. Their hide gives a natural AC of 14+Dex modifier. When they receive an ability score improvement from their class, they may instead raise their AC by 2, to a maximum of 20.
Tail: When only attacking with her thagomizer, a Stegoman's tail does 1d10 damage on a hit. It can also be used as an off-hand weapon for 1d4 damage. The regular weapon the Stegoman wields does not need to be a light weapon, but it does need to be one-handed.
About Stegomen: There are no sub-races of Stegomen, there are only Stegomen. Males and Females are indistinguishable to non-Stegomen. Subtle variations in the color of back plates clearly identifies sex to other Stegomen.
