Depends on the monster.

Godzilla's designs have varied throughout the years. The scariest costumes (that I can think of.) are 1954, 1964, 1984, 1989, 1995, 2001, and 2016.

Mothra, in general, may or may not freak you out 'cause she's literally a giant insect (especially classic Mothra from 1961.).

The only genuinely scary costume for Rodan I can think of is his 1956 costume from his debut movie, since it looks like an actual pterodactyl.

Like Rodan, the only genuinely scary Anguirus costume I can think of is his 1955 costume from Godzilla Raids Again, his first appearance.

But those are only a select few monsters, and their designs vary radically. The scariest monsters I can think of outside of Godzilla or his supporting cast are Hedorah, Gigan (2004 in specific.), Biollante, SpaceGodzilla, Orga (when he tried to eat Godzilla whole in the movie.), and Destoroyah.
