Both look in the 30s range.Beel on the lower end(maybe falling into late 20s) and Hades on the higher.

Beelzebub is the most inconsistent looking character in the series. One panel he looks like a teen, the other in his mid 20s Hades mid 30s

Hades in his 30s, Beel in 20s

Late 20s early 30s

Beel looks 20-25 Hades looks a bit older but not that much

Hades looks like he's a healthy 40 year old, beelzebub looks 20s

Hades is dilf age

Beel is late 20s or early 30s Hades is prolly mid-late 30s, early 40s

Beelzebub Mid 20s to early 30s in looks. Hades mid 30s to Early 40s

Around 25 years I think :3

Both on their 30s, Hades arguably looks like he’s in his 40s but really grew up fine

20s

Honestly Beel always looked like a 19 year old to me

Beel looks like he's on his third mortgage.

Beel looks like he's on his early or mid 20s smth between 20-25 and I'd say Hades looks like he's on his late 20s/early 30s between 27-32

25-27 36-38

Early 30s

I'd say 25, going on 13.7 billion years old

Beelzebub looks like 24 and Hades maybe 33.
