They aren't.  You're being fooled by the default output format of
hexdump.  By default, it displays data as 16-byte integers in
little-endian.  If you want to look at bytes, do this:

$ python2.7 -c "print('\xfd\x84\x04\x08')" | hexdump -C
00000000  fd 84 04 08 0a                                    |.....|
00000005
