If you sent your key to a keyserver, then you are out of luck. There
is no way to take something back you sent to a keyserver. You can
only revoke things, but to add a revoker is unrevocable itself for
security reasons. The only possibility for you is to revoke the key
by yourself, but that is also the only damage a bad revoker can do to
your key, so ...
As the addition of a revoker to a key is the addition of a signature,
there is a non-trivial way to get rid of it, when and only when you
kept the key for yourself. If this is the case, ask again and I will
send you instructions.

>From the man page (= manual):
--ask-sig-expire
--no-ask-sig-expire
When making a data signature, prompt for an expiration time.
If this option is not specified, the expiration time set via
--default-sig-expire is used. --no-ask-sig-expire disables
this option. Note that by default, --force-v3-sigs is set
which also disables this option. If you want signature expi-
ration, you must set --no-force-v3-sigs as well as turning
--ask-sig-expire on.
--default-sig-expire
The default expiration time to use for signature expiration.
Valid values are "0" for no expiration, a number followed by
the letter d (for days), w (for weeks), m (for months), or y
(for years) (for example "2m" for two months, or "5y" for
five years), or an absolute date in the form YYYY-MM-DD.
Defaults to "0".

>From the man page (= manual):
--list-options parameters
This is a space or comma delimited string that gives options
used when listing keys and signatures (that is, --list-keys,
--list-sigs, --list-public-keys, --list-secret-keys, and the
--edit-key functions). Options can be prepended with a `no-'
to give the opposite meaning. The options are:
(...)
show-sig-expire
Show signature expiration dates (if any) during
--list-sigs or --check-sigs listings. Defaults to no.
The options I cited from the man page can be used on the commandline
every time you need them or you can put them in the configuration
file for gpg (gpg.conf) so that they are invoked every time you use
gpg.
