Manny Heffley

Manny Heffley is Greg and Rodrick's younger brother, and a major antagonist in the Diary of a Wimpy Kid franchise.

Why He Sucks

 * 1) He knocked the power out of the house, and almost murdered the Heffley family because no one taught him to tie his shoes!
 * 2) He throws tantrums very easily.
 * 3) He pretty intelligent for a baby (like Stewie Griffin, soon to be on the Great Characters Wiki) he hacked Greg's internet account and changed the password.
 * 4) He's more annoying than Greg and Rodrick combined!
 * 5) No one was brave enough to stand up him. Not even Susan and Frank.
