[Puzzle] A Puzzle a Day #1 - Back to the Classics (5 Characters)

For the next 30 days, or until I finish the next group event, whichever comes first, I will release one puzzle every day. First up is a blast from the past - a format unused since itstoohard came into prominence.

_oinks (Shaggy)
Head of MI6
Me
Right half of eight
sqrt(-1) in EE

XXxXx
X can be a number

Rules:
I can't believe I actually have to make this section, but apparently there are people who don't know the rules. Do not share answers, hints, giveaway links, the name of the giveaway or generally spoil the puzzle in any form.

Added incentive: If you solve at least half (15) of the puzzles, you will get an invite to a private giveaway at the end of July. Post in the giveaways as proof. I'll try to pick something that no one has already, but no guarantees.

Solution will be posted after giveaway #30 ends.

Solution:
Zoinks - phrase from Shaggy from Scooby Doo
M - Head of MI6 in the James Bond series
I
3
J - EE is Electrical Engineering, use j because I conflicts with current.
